SPECIFICATION forming part of Letters Patent No. 439,335, dated October28, 1890. Application filed November 30, 1888.Y Serial No. 292,192. (Nomodel.)

' Quincy, in the county of Scott and State of Illinois, have inventedcertain Improvements in Ealing-Presses, of which the following is aspecification.

This invention relates to that class of socalled continuous presses inwhich the charges are introduced through aside opening into a trunk orbody, where they are carried forward successively by a reciprocatingplunger or traverser and added to the preceding mass which is graduallydelivered from the opposite end of the trunk.

The principal objectsrof the invention are to give the operator perfectcontrol of the action of the plunger and to economize the application ofpower to the machine.

In the accompanying drawings, Figure lis a longitudinal section througha press constructed on my plan, on the line o0 of Fig. 2, the extremedelivery end, which is of ordinary construction, being broken away toreduce the size of the ligure. Fig. 2 is a front end elevation of themachine. Fig. 3 is a side view of the primary driving-shaft and itsconnections.- Fig. 4 is a cross-section of the same on the line y y.Figs. 5 and 6 are respectively a side view and a plan view of thesectional safety-pitman.

Referring to the drawings, A represents the horizontal trunk or body ofthe machine, constructed, asusual,with a strong external frame` work anda top opening ct, into which the successive charges of hay areintroduced, and from which they are driven one after another through thetrunk toward the delivery end, commonly known as the rear end.

B represents the plunger or traverser arranged to reciprocate within thetrunk, past and beyond the eedppening, for the purpose of carrying thecharges rearward and adding t them to the accumulated mass beyond.

In presses of the present type as ordinarily constructed the plunger ortraverser is of box-like form, and consequently its front end whenretracted must stand forward of the driving-gear, which necessitates theconstruction of a very long frame to accommodate all the parts. Insteadof constructing the plunger in its usual form, I build it, as shown,with a compar. tively thin vert-ical face, and with a horizontal arm bextending :rigidly forward from its upper side. This arm runs at theupper side within the top `of the trunk or chamber and is guidedthereby. On the under side the arm overrides and is supported by one ormore rollers b4, secured to theinner sides of the frame. In place ofthe'two rollers b4 a single roller extending across the inside of theframe, or a cross-bar in the same position, will answer the purpose, theonly requirement being that the arm shall be guided and supported on theunderside so as to prevent it from dropping downward. The rollers orother guides are so located as to admit of the arm b passing over themand of the face of the plunger retreating until it nearly reaches them,as shown in Fig. l. Owing to the fact that the plunger is without theusual forward extension at the under side, it may pass rearward, asshown in Fig. l, over the top of the driving-gear- This permits thedriving-gears to be placed farther rearward than usual-in other words,closerl to the feedopening than in ordinary machines--and consequentlyenables me to materially reduce the length, width, and expense of mypress. If desired, one or more rollers be may be placed at the loweredge of the plunger to travel ou the floor of the trunk, and thus reducethe friction. As the plunger advances it will sometimes happen that thecharge before it will rise above its upper edge and prevent its advancebeyond the rearward side of the feedopening. To overcome thisdifficulty, I provide the plunger at the top with a vertical yieldingplate b, which may be constructed and applied in any suitable manner. Asshown in the drawings, the plate, preferably of metal, is hinged to thetop arm of the plunger at b2, and supported at its rearward end byspiral springs b3. y Under ordinary conditions If the hay overrides itsrearward end during its advance, it will yield in a downward directionand permit the plunger to continue its movement.

The plunger is actuated by a pitman C, jointed at one end thereto andjointed at the opposite end to an arm D, mounted on a horizontal shaftE, sustained firmly in the frame.

D, and mounted at theopposite end on a the plate is held against the topof the trunk.

IOO

A pitman F is jointed at one end to the arm crank-pin g. This pin isattached at its opposite ends to two vertical gear-wheels G and G',which are mounted within and at opposite sides of the frame on shortstuds or journal g', fixed thereto, this arrangement perinitting thecrank-pin and the end of the pitman F to make a complete revolutionbetween the two wheels.

The wheels G and G', which are entirely independent, except as to theconnecting-pin g, are driven, respectively, by pinions I-l and H',mounted within the frame near `opposite ends of a shaft I, which latteris seated in stationary boxes or bearings at the base of the frame.

The shaft I, which is the primary drivingshaft, is provided at one endwith a universal joint` or coupling J, by which it may be connected tothe tumbling-rod of a horse-power or`to any other suitabledriving-shaft.

As it is sometimes desirable to make the di'ivingconnections at tlieendof the machine, the shaft I is provided at one end with a bev.- eledpinion t', engaging a pinion t" on the end of a shafti2, which latter isextended lengthwise of the frame through suitable bearings thereon, oneend being exposed and provided with a suitable coupling Vhen the shaft Iis re volved, its pinions rotatethewheels G G',which in turn carry thecrank-pin gin a circular path. The crank-pin, through the pitman F,actuates the arm D and pitman C, causing the plunger or traverser tomove forward and then retreat at each revolution of the Wheels G G'. Asthe plunger or traverser advances the pitman C and arm D act after theman- -ner of a toggle or knee-lever.

In order that the driving-pinions may be thrown out of action and themotion of the press arrested without stopping the drivingshaft, thepinions H H' are mounted to turn loosely on the shaft and are adapted tointerlock, respectively, with the clutch members 7L 71,', splined to theshaft to move endwise thereon. These clutches may be toothed, or theymay be of the familiar frictional type, as preferred. Each clutch memberh 7L is provided with the usual hub having the circumferential groove,and the two clutch members are thrown into and out of actionsimultaneously by an intermediate lever h2, having pivoted plates h3,which engage the grooves in the hubs of the clutch members h h'. A rodh4 extends from the lever to any point from which it may be convenientlyoperated by the attendant.

The shaft I is provided at one end with a large spur-wheel K, fixedthereon and engaging a pinion L on one end of a shaft M, which isextended transversely through the machine and provided at the oppositeend with a heavy y-wheel N.

In order to feed the successive charges into the machine, I mount on thetop of the frame near one end levers O, provided at one end with thefeed-blades P and connected at the opposite ends by rods Q to an arm d,extending rigidly and laterally from the arm D. The relative positionsof the parts are such that the arm d and rods Q cause the feedplates Pto desc-end through the feed-opening when the traverser is retracted.

The rods Q are constructed in a telescopic manner at the upper end andprovided with spiral springs q, tending to elongate them, or areotherwise provided with springs to admit of the lever O yielding in anupward direction in the event of the feed-blades encountering anexcessive resistance.

It sometimes happens in practice that the resistance offered to theadvance of the plunger is such as to cause undue strain on the operativeparts. To avoid danger from this source, I construct the pitman F intwo'parts, its body portion f being inserted endwise be# tween the twoplates f', which'form its head. These plates, which encircle thecrank-pin, are drawn forcibly togetl er on the portion f by bolts f2,the friction being suoli as to maintain the connection of the partsunder ordinary circumstances. When the strain is excessive, it willovercome the friction and the body portion f will be drawn out frombetween the plates f', thus disconnecting the driving-gear from theplunger.

It is to be observed that in the operation of my press power is applied,primarily, to the pinion-shaft I, and transmitted thence through itspinions directly to the wheels G G', which carry the crank-pin foroperating the toggle mechanism of the follower.

It will be noticed that motion is transmitted from the gear on thepinion-shaft I directly to the shaft which carries the fly-wheel, sothat the fly-wheel receives motion from the driving-shaft independentlyof the gearing which actuates the plunger. The fiy-wheel is made ofgreat weight and the gearing so proportioned as to impart very highvelocity thereto during the retreat of the plunger. The momentum of thefly-wheel is applied through the intermediate gearing to assist inadvancing the plunger. Thus it is that the power applied during theretreat of the plunger and while the parts are running free is renderedavailable in the compression of the hav.

Owing to the fact that the ily-wheel remains in gear with thedrivingshaft, although the plunger-operating gear is thrown out ofaction` I am enabled to continue the motion of the drivingshaft,although the plunger-operating gear is driven intermittin gly. This isfound in practice to be a great advantage.

I am aware that the primary driving-shaft of a baling-press has beenprovided with ilywheels and connected with the pressing mechanism by anintermediate clutch, so that the shaft, continuing its motion, would actto turn the fly-wheels and thus store up energy during the time that thepressing mechanism was out of action, and to such construction I lay noclaim.

IIO

The peculiarity of lnyinvention lies in the fact that the driving-shaftis connected on the one hand through a clutch mechanism with thepressing devices and on the other hand through intermediate speedinggear with the fly-wheel, so that the ily-wheel will receive a muchhigher velocity than the driving-shaft. This arrangement is highlyadvantageous in'that the speed of the drivingshaft is and must becomparatively slow, so that when fly-Wheels of practicable size areapplied directly thereto a few revolutions of the shaft will give themtheir maximum speed, after which there is no further conservation ofenergy. When, however, the y-wheels are geared to the driving-shaft, asherein shown, a considerable time is required for them to attain theirmaximum velocity, and thus the accumulation of energy may be eX- tendedover practically the entire time between the binding of one bale and thenext.

Another advantage in my arrangement lies in the fact that theiiy-wheels, having high velocity, act through intermediate powergear toimpart a comparatively slow motion to the pressing devices, theapplication of the accumulated energy being thus distributed over aconsiderable period of time and the parts enabled to act moresatisfactorily than would otherwise be the case.

l am aware that the operating-pit-man of pressing mechanism has beencomposed of separable parts united by a wooden breakpin intended to besheared off by excessive strains, and to this construction I lay noclaim, my invention in this regard being limited to a pit-man theseparable parts of which are held together solely 'by frictionalcontact, so that they may be separated without breaking or shearingaction and reunited without the employment of new or additional parts.

Having thus described my invention, what I claim is l. In a baling-pressof the type herein described, the horizontal trunk or chamber,gear-wheels G G at the front end, the plunger or traverser having at itstop the rigid front arm to override the gear, the stationary guidebeneath said arm, a pitman jointed to the plunger, and suitableintermediate connections for transmitting motion from the Wheels G G tothe pitman, substantially as described.

2. In a baling-press of the type herein described, the driving-shaft,the plunger, and intermediate power-gear and its connections for slowlyadvancing the plunger, clutched to the driving-shaft that it may bedisconnected therefrom at will, a ity-wheel, and intermediate speedinggear permanently connecting the fly-wheel with the driving-shaftindependently of the gearing through which the plunger isoperated,whereby the drivin g-shaft may be continued under motion andcaused to impart a high velocity to the ity-Wheel, while theplunger-operating mechanism is ont of connection and the momentum of theiy-wheel thereafter rendered available to slowly=ad vance the plungerthrough the intermediate power-gearing.

3. In a baling-press, the plunger, the pitman C, and arm D for operatingthe same, the pitman F, the two gears G G', and the crankpin foroperating pitman F, the driving-shaft I, its pinions H H', and theirclutches for driving the before-mentioned gears, the flywheel, its shaftand pinion, and the gear K, mounted on the driving-shaft.

4t. In a baling-press, the plunger, the plunger-operating crank, meansfor turning the same, and an intermediate pitman composed of twoseparable parts united and held together solely by frictional contact,substantially as described, whereby the parts are permitted to separateand relieve the crank in the event of the plunger meeting with excessiveresistance.

5. In a baling-press, and in combination with a plunger and anoperating-crank, means for turning the same, an intermediate pitmanconsisting of the body portion f, the two portions f, adapted toencircle the crank-pin and embrace the portion f, and thetightening-bolts f2, connecting the parts and holding the same 'infrictional contact with the body portion,

whereby the parts may be adjusted to separate when the plunger meets agreater or less resistance.

In testimony whereof I hereunto set my hand, this 12th day 'of November,1888, in the presence of two attesting witnesses.
